Electricians NEC Toolkit

Electrician's NEC Toolkit replaces a phone full of single-purpose calculator apps with 10 core code-compliance tools in one place, all keyed to NEC 2023: • Residential Load Calculation (Article 220) • Commercial Load Calculation • Branch Circuit Sizing • Motor Calculations (Article 430) • Panel Schedule Builder • Voltage Drop Calculator • Wire Size Selector • Box Fill (314.16) • Conduit Fill (Chapter 9) • Full NEC Reference Tables WHY ELECTRICIANS KEEP THIS ON THE TRUCK Save every calculation to a project, come back later, change one input, and re-run it — nothing gets locked into a static PDF. Export clean, professional job reports ready to share with an inspector or client. BUILT ON THE CODE, NOT A GUESS Every table — ampacity, conductor properties, demand factors — comes from NFPA 70 (2023), verified cell-by-cell against the printed code book. TRY EVERYTHING, FREE 7-day full-feature trial — every module, unlimited saved projects, unlimited PDF exports, no watermark. After the trial, one simple one-time purchase unlocks full access. No ads. No subscription. No tracking. Available in English and Spanish. This app is a field reference tool and does not replace the judgment of a licensed electrician or the authority having jurisdiction (AHJ). Always verify calculations against the NEC edition adopted by your local jurisdiction.
